Sky Map is a hand-held planetarium for your Android device. Use it to identify stars, planets, nebulae and more.

Originally developed as Google Sky Map, it has now been donated and open sourced.

Troubleshooting/FAQThe Map doesn't move/points in the wrong place
Make sure you haven't switched into manual mode. Does your phone have a compass? If not, Sky Map cannot tell your orientation. Look it up here: http://www.gsmarena.com/

Try calibrating your compass by moving it in a figure of 8 motion or as described here https://support.google.com/gmm/answer/6145351.
Are there any magnets or metal nearby that might interfere with the compass? Try switching off "magnetic correction" (in settings) and see if that is more accurate.
